Overview
The Head-to-head analysis for Likelihoods shows how events compare to each other with respect to a Threat.
In Riskion, we refer to threats, causes, hazards, and sources interchangeably. While they may have slightly different nuances depending on the context in which they are used, they serve the same purpose -- they are all threats/sources of risk (for Risk Events) or sources of opportunity (for Opportunity Events).
In our sample model, we are using the terminology "Source(s)".
Head to Head Analysis for the Overall Events Likelihoods
One event is listed on the left side of the graph and the other is listed on the right. Down the middle of the graph are listed the sources in the model. If the left-hand event is preferred to the right-hand event given the source, a horizontal bar is displayed towards the left. If the right-hand event is better, the horizontal bar will be on the right. If the two events are equal, no bar is displayed. The overall result is displayed at the bottom of the graph and shows the overall percentage that one event is better than the other; this is the difference.
You can change the events being compared using the pull-down menu:
or by clicking the 
icons.
By selecting an element in the hierarchy other than the top node, you can see the results due to this element rather than the overall results due to the "Sources" node.

Select Participants and Groups
You can select to display results for one participant or group using 
Clicking the 
button will open a window where you can select a participant or a group.
You can use the prev
and the next 
buttons to cycle through each participant or group.
Filter Events
By default, all events are displayed.
You can select to display the top or bottom 5, 10, or 25 events based on the "All Participants" group likelihoods.
The Advanced filter, allows you to select a specific number for the top N, and base it on another group or participant.
The select /deselection option, allows you to check/uncheck the events.
The filter by events attributes, filter the events base on the attributes specified on the Events page.
The show risks only / Show opportunities only are applicable for the Mixed model where events can be Risk or Opportunity.
Advanced Mode Options
When the Advanced mode is ON, you will see the advanced options of the page you are currently working on.
1. Combined Input Option (CIS)
If the Combined Input Option (CIS) is ON then results for individuals are computed by combining the likelihoods (or impacts) derived from judgments/ratings for which they had roles, with the combined results for any parts of the model where they did not have a role.
2. Apply User Priorities
If priorities (weights) have been specified for participants, you can use the "User Priorities" check box which enables you to apply or ignore these priorities in calculating the results.
3. Synthesize Events WRT top-node
This option is available on all the Sensitivity screens and can only be enabled when a non-covering node other than the top node is selected on the hierarchy tree.
Enabling this option allows to temporarily change the likelihood (or impacts) of the children of the selected node and see how these changes will affect the overall likelihood (or impacts, or risks) of the events. If this is OFF, we can then see the change of the likelihood (or impacts, or risks) of the events WRT the selected node.
